bug宝典JAVA篇 BeanUtils.copyProperties 日期问题

执行BeanUtils.copyProperties(dest, orig);的时候出现下面的错误，我的代码如下,主要目的是复制对象，但是又不想一个个set,下面的BeanUtilsExtends是照着copyproperties 谁赋值给谁抄的，实际运用却出现下面的问题

@Transactional(readOnly = false)
    private boolean createNewRecord(FontalMaintainLog record, Date nextOptDate){
        FontalMaintainLog newRecord = new FontalMaintainLog();
        BeanUtilsExtends.copyProperties(newRecord, record);
        newRecord.setId(StringUtil.getUuidString());
        newRecord.setOptDate(nextOptDate);
        return insertSelective(newRecord);
    }

Caused by: java.lang.ClassCastException: java.util.Date cannot be cast to java.lang.String

debug发现，红色方框内容有问题，本来arg1就是日期类型，转字符串自然就报错了。

稍作调整如下：
